Police say the search just northeast of the bedroom community of Airdrie is connected to the disappearance of five-year-old Nathan O’Brien and his grandparents, 66-year-old Alvin Cecil Liknes and 53-year-old Kathryn Fay Liknes.

On Friday night, a man who lives on the acreage was taken into custody for questioning.

“This is just an investigative step. It’s not something where we’re certain this is the fellow,” Duty Insp. Joel Matthews explained at the time. “We are just following up a tip, so it may not lead to where we wanted to lead and this might not be related.”

Sources tell Global News he is 54-year-old Douglas Garland, and he remains in police custody on an unrelated matter. It’s believed that he has links to the Liknes family.

He is scheduled to appear in court on Monday, to face a fraud-related charge. Calgary Police say he is still considered a person of interest in the missing persons case.

Investigators expect to continue searching the property over the next couple of days, and are trying to determine if a vehicle seized from the home is linked to the case.
